Title: Rear wheel steering device for vehicle
Inventor: NAGAI MICHIYUKI
IPC: B62D5/04
Filed: 1995-09-28
Abstract: PROBLEM TO BE SOLVED: To strengthen toe rigidity, save energy, and reduce the cost by providing an offset rotor connected to an inner shaft pivotally supported in an external sliding body via an eccentric pin on a small-steering angle steering means in a rear wheel steering device provided with the small-steering angle steering means and a large-steering angle steering means. SOLUTION: When a controller judges that the actual vehicle speed becomes lower than the set vehicle speed, the drive of a small-steering angle steering means 29 is stopped. When a steering handle 25 is operated at this time, front wheels 22 are steered via a power steering device Z3, and rear wheels 24 are steered via a rotation transmission system 28 and a large-steering angle steering means Z8. When the inscribed cam of the large-steering angle steering means 28 is rotated around the first center line, a pair of cam followers, an outer tube, the small-angle steering means 29, and an inner shaft 27 are slid in the vehicle width direction B, and the rear wheels 24 are steered. In the travel area exceeding the set vehicle speed, the electric motor of the small-steering angle steering means 29 is driven, and the feedback control of the rear wheel steering angle is conducted.

Title: Reel base rotation detecting device
Inventor: INOUE HIDENORI
IPC: G11B15/093
Filed: 1985-11-08
Abstract: PURPOSE:To correctly perform the measurement in the number of rotations by detecting the change in a photo-current and by starting the current of LED with positive feedback so as to increase it in case of the reflectance being big and to reduce in case of small reflectance. CONSTITUTION:A reflecting plate 12 is set up on a reel base 11 and the rotation of the reel base 11 is detected by a photo-sensor 13. The electric potential of output voltage V33 is raised because of the potential of the reverse input voltage V31 of an amplifier 2 being lowered in case of the photo-current becoming large, and becomes large with its flow to LED. In case of the photo-current becoming large in this way, the potential of the potential V31 is lowered further. The potential of the potential V33 is raised and the current which flows to LED becomes small due to the potential V31 being raised in case of this photo- current becoming small. Therefore the photo-current becomes smaller further and the potential V31 is raised further. In this way the shaping of the output waveform can be performed by providing the circuit that varies the LED current by the big or small of the photo-current.

Title: Vram data read method
Inventor: IZUMI ISAMU
IPC: A63F13/06
Filed: 1992-08-27
Abstract: PURPOSE:To read data at a high speed by storing data, which indicates the state of characters, in a virtual VRAM provided on a main memory and reading in data indicating the state of characters from the virtual VRAM. CONSTITUTION:BAT and CG indicating the background and SAT and SG indicating sprites are partially extracted and copied from a VRAM to the virtual VRAM. Only picture information to be frequently used is copied from the VRAM to the virtual VRAM and is managed in the virtual VRAM. In the case of detection of the position of a display material or the discriminating processing of collision between materials, it is necessary to read contents of the picture; and in this case, the virtual VRAM is used, and the VRAM is not directly read but the virtual VRAM is first read to discriminate the processing to be next executed. Consequently, this method copes with most processings with the virtual VRAM because principal picture information is equally stored in the VRAM and the virtual VRAM, and the read speed is considerably increased.

Abstract: PURPOSE:To bury the interior of a groove completely with an insulating film by making its shape to be of a channel section which is tilted to the surrounding surface of the groove opening by a primary insulating film and by applying a secondary insulating film thereon to bury the groove. CONSTITUTION:A channel 4 which has perpendicular side walls is shaped in one main surface of a semiconductor substrate 1 and a primary insulating film 11 is applyed on the main surface of the substrate 1 and the inside walls of the groove 4. The groove 4 is buried thereafter by applying resist 12. Then resist 12 is eliminated remaining a part thereof in the groove 4 to remain a part of the insulating film 11 within the groove 4. The primary insulating film 11 is etched and eliminated so that its main surface tilts to the surrounding surface of the opening of the groove 4. The remaining resist 12 in the groove 4 is then eliminated. A secondary insulating film 13 is coated all over the substrate to bury the groove 4. When the secondary insulating film 13 is deposited within the groove 4, the effect of the deposition difference in the groove 4 is thereby minimized and voids can be avoided.
